GRAIN-BIN 'DOOR.

Specification of Letters Patent.

PatentedDec, 5, 1911.

vApplication filed July 17, 1911. Serial No.',638,837.

To all whom it may. concern:

Be it knownthat I, VICTOR W.. JANsEN, of North Bend, in'Dodge county, inthe State of Nebraska, have invented certain new and useful Improvementsin Grain-Bin Doors,whioh improvements are described in the followingspecification and are illustrated by the accompanying drawings.

The invention relates in general. to doors for grain bins and other likereceptacles, and relates in particular to those doors of this classwhich comprise a door casing, a slide in the casing and a hingedorswinging chute attached to the casing.

It is the object of the invention to render doors of thisclass and kindsimple and easy of construction and operation, durable and i not easy toget out of order, free from leakage, and complete and secure in theirclosure; to close the casing by the slide in such a door, and alsoadditionally to close the same independently of the slide; to utilizethe chute as a cover of the slide; to inclose the slide completely, whenthe door is not in use; to cover and inclose the delivery end of thechute, when not in use; and in general to produce a superior grain-bindoor of the kind above specified. To accomplish these results, Iincorporate in my improved door a casing that projects from the sidewall of the bin, a slide that works vertically in this casing, anoverlapping chute that is hinged to the bottom of the casing, and ahinged cover that overlaps the top of the casing as well as the top ofthe slide and the upturned delivery end of the chute.

The best manner in which I have contemplated applying the principles ofthe invention, is shown in said drawings; but, as some changes can bemade in the construction of the door, and some apparently differentembodiments of these principles, without departure from the scope orspirit of the invention, it is intended that all matters contained inthe following description, or shown in these drawings, shall beinterpreted as illustrative and not in a limiting sense.

In these drawings, Figure 1 is a front elevation of a complete door thatis constructed in accordance with these principles; in this view thedoor, mounted on a vertical wall of a grain bin, is shown with the chutelowered into position for use, and with the hinged cover lifted wideopen. Fig. 2 is a side elevation of the same door mounted in thesamemanner ;in this view thejhinged chute in its closed position, is shownin full lines, andthe same in its open position, is

.shown in broken lines; and the same holds true as to the hinged cover.Fig. 3 isa horizontal section on the section line OO of Fig. 2. Fig. 4:is a central vertical,sec-' tion on Fig. 1. p

In these figuresthe numeral 1 'denotes a portion of a vertical wall ofthe grain bin.- Continuous with this .wall, and projecting outwardtherefrom, is formed the rectangular door, casing,,havingthe verticaland parallel side walls '2, and having the parallel top.and bottom fiatplates, 3 and l, inclining slightly downward from their inner to theirouter edges, as shown in FigsQQand l'. The swinging chute, open at thetop and at each end, is external to the door casing. It has the flatbottom 5 and the vertical sides 6, and is hinged to the underside of thedoor casing by the hingepin 7 which passes through the vertical chuteside 6 at a dis tance from the inner end of the chute, less than thedistance of that pin from the face of wall 1, and also passes throughthe sleeve bracket 19 at the lower forward edge of the bottom casingplate 4:. The chute carries an external staple 8, and, like other partsof the device, is suitably reinforced.

A vertically sliding door 9, preferably comprising the duplicaterectangular sections 9 fitted to close edge contact with each other, isseated across the opening of the door casing, and works in verticalgrooves 10 formed along the outer edges of the casing walls 2respectively. This door is provided with handles 11 for the purpose ofoperating the door to open and close the doorway to any desirable extentas occasion may require.

The cover 12, being of rectangular form, A

wider than thechute, and comprising connectedly the main plate 13, theend plates 14 and the edge plate 15, is hinged by pin 16 and sleevebracket 17 to the door casing in a location just back of the path of thevertically sliding door sections 9, and is provided with an externalcatch 18, which is adapted to engage the staple '8 on the back of thechute.

In the operation of the invention, the chute, when occupying itsinclined working position, reaches back for a distance under the outerend of the projecting door casing, and thereby prevents leakage orescape of grain between the casing above and the chute below. When inthat position the chute is fulcrumed upon a very firmly supportedportion of the door casing, and also exerts the upward thrust of itsinner end, or short arm, under that portion of the door casing which isadjacent to the supporting wall 1; consequently the structure is notunduly strained or bent by the weight or leverage of the chute and itscontents.

When occupying its vertical position the chute is folded over andoutside the casing walls 2, and may be there secured by the overlappingand inclosing cover 12, fastened by catch 18, engaging staple 8. In thisway the sliding door is inaccessibly covered and inclosed.

I claim as my invention A grain-bin door of sheet metal, comprising arectangular downward sloping door casing projecting out from the side ofthe bin and continuous therewith, aninside door slidable vertically ininside grooves formed in the sides of said door casing, an overlappingpivoted chute fulcrumed as a lever on said casing in a positionalternatively to hug with one arm of the lever the outer end of saidcasing and with its other lever arm to hug and exert leverage along thesloping bottom of the same, a swinging and overlapping cover hinged tothe top of said projecting casing behind the path of said insideslidable door in a position to engage the outer end of said pivotedchute by overlapping the sides and bottom of the same, and means forfastening said swinging chute and said overlapping cover closed unitedlytogether over the top, the sides and the outer end of said projectingdoor casing. y

In testimony whereof I hereunto set my signature in the presence of twowitnesses.
